When you use the basic Organize feature to color messages, the Display Name
property on the message's "To" or "From" line is used to select the item.
The presence of commas, spaces, and quotation marks in the display name
determines how the Organizer treats the elements of the name.
To use the Basic Organizer Feature to Color Selected Messages
On the Inbox Tools menu, click Organize.
In the Organize area, click Using Colors.
In the "Color messages" section, click to select "from" and type the
name of the person whose messages you wish to color.
NOTE: The following describes how commas, spaces and quotation marks
will affect the treatment of the name entered:
If a name is entered with a comma separator, such as "Doe, John"
(without the quotation marks), the comma is treated as an OR, and the
entry is interpreted as two names. In this case the entry is treated as
either Doe OR John and all messages including either of the values, Doe
OR John, such as Mary Doe and John Smith, will be colored.
If a name is entered with a space separator, such as "John Doe"
(without the quotation marks), the space is treated as an AND, and the
entry is interpreted as two names. In this case the entry is treated as
John AND Doe and all messages including both of the values John AND
Doe, such as John Doe Jr., and John Robert Doe, will be colored.
If a name is entered enclosed in quotation marks, such as "John Doe"
(WITH the quotation marks), it will be treated as a single name and the
names John and Doe must appear together in order to qualify for
coloring.
